IMPROVEMENT IN cassettes,

{the snout nftrnhtt in that 'itittts hunt mu mating part at the smut;

TO ALL WHOM IT MAY CONCERN:

Be it known that I, Gouvrou G. GnIswoLD, of the city, county, and Stateof- New York, have invented certain new and useful Improvements inUmbrellas; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

My invention relates to the construction of the notch or crown-piece andrunner to be used in umbrellas; the devices which secure the ribsanilstretchers to or in the notchor crown-piece.and runner respectively; tcthe spring-catch which fastens the umbrella either open or shut; and tothe construction of the inner ends oi the ribs and stretehers, to adaptthem tobe used with the notch .or crown-piece and runner as improved.

My object is to produce an umbrella cheaply, which shall be neat anddurable, and the notch or crownpiece and runner of which shall be soconstructed and arranged with reference to the ribs, and stretehers thata rib or a stretcher may easily be removed when broken and its placesupplied by another.

My invention consists-- First,'of a notch or crown-piece, made with anannular groove in the inside of one end ot'it, and slots cut throughinto'said groove, through which the ends of the ribs pass, which endsare made T-shapcd, so as to beanagainstihemllaofi the. sa d groove ateach side of the said slot, and thus held the saidribs from drawing outradially, and in the combination therewith of an annular piece ofrubber, or other flexible yielding substance, which is plaeed betweenthe inner edge of the wall surrounding the said annular groove and thetube or staff of the umbrella, and partly within the said groove, tosecure the ends ofthe said ribs from coming out, sub stantially ashereinafter set forth. That portion ofthe runner which receives the endsof the stretchers is made similar to the notch or crown-piece, as abbvedescribed.

Second, in the combination with the notch or crown-piece, made as abovesetforth, of a metal or leather. ring, having a. notch or crown-piececut into it, or a. piece or portion removed from it, so that the saidnotch or crown piece may be moved opposite each or either of the slotsin the wall of the said annular groove, 'so as to admit of the insertionor withdrawal of one or more of the ribs when desired, for repairs, &c.,the said metal "ring being set within the groove, or against theopening, and serving to close the opening between the walls of theannular, groove and the tube or staff, substantially as hereinafter morefully set forth Third, in the combination with the runner, made as aboveset forth, of suitable spring-catches, which pass down through the wallsof the annular groove in the said runner, and are supported in slotsmade therein, and which. are held down in position by the rubber ringwithin the runner, substantially as hereinafter more fully set forthFigure 3 is a section showing the parts-above the line x :e, fig. 1.

Figure 4 is a detail view of ,a tube or stnfi', with a notch orcrown-piece having a metal ring in it, and a runner with spring-catches,difif'ernt in form from those shown in fig. 1.

Figure 5 is an underside view ofthe notch or crown-pieccseen in fig. 4.

Figure 6 is a topview oi the runner seen in fig. 4.

Figures .7, 8, 9, and 10 show in detail different forms which may begiven to the ends of the ribs and stretehcrs, to fit them for the notchor crown-piece and runner.

Figure 11 is a side elevation in detail of one of the spring-catchesseen in fig. 1.

Figure 12 is another form or modification of the notch or crown-piecewith metal ring.

Figure 13 is a radialsection of a runner in which a metal ring is usedwith the slotted groove.

A is the staff of the umbrella; B B are the ribs; C C are thestretchers; D, the notch or crown-piece, and E the runner. F is asleeve, having a groove and shoulder in its surface for the springcatches G to hook into when the umbrella is raised or spread, andH is a.similar slecvc, for the said catches to hook under when, the umbrella isclosed. I is a rubber ring, which. serves in the runner to hold theends'of the stretchers from slipping out of their seats, and also tospring the catches G G intotheir places, and to hold them there. J is aring of rubber, or other sufliciently yielding substance, which beingthrust into the opening betwcenthe secafterwards returned to itsoriginal position.

tions at a of the walls of the groove in the notch or crown-piece D, andthe stat? A, prevents the ribs from work ing out,while it may be eithercompressed or removed sufliciently to permit of the withdrawing of a ribor the inserting of another in place of the one rcmovedfor repairs, 8:0.

The spring-catches G G are made in the form shown in figs. 1 and 11,having books at each end, to hook into the sleeves above and below, forthe purpose of fastening the umbrella either open or shut, as may bedesired. Near their upper ends they are both made semi-cylindrical inform for a short distance, just at that portion which .comes under therubber spring I, (as seen at b, fig. 11,) for the purpose of furnishinga suitable bearing for the spring I, and to prevent itlfr'omrubbing'against the shaft as the runner is moved up or down. Thespring-catches G G are kept from slipping up or down by a groove on theinner side of each, which fits snugly over a projecting fillet or beadon the runner, as seen at c, fig. 1, and '01, fig. 4. This fillet alsoserves as a fulcrum for the'spring-ca-tches G G. I i

The ordinary form of springcatches may be used, and therubbcr ring Idispensed with, using instead thereof a. metal or other suitable ring,as seen in fig. 13, in which K is the runner, and L. the ring,.which hasa notch or crown-piece, 7c, in one side of it. Whenever the notched ringg or L is used, it may have one or more notches in it, but I prefer tohave but one, as that'is sufficient.

In order to remove a broken or damaged rib or stretcher from the notchor crown-piece or runner shown in figs. 1, 2, and 3, or from the runnershown in fig. 4, the centre ring, I or J, as the case may be, is forcedup out of the groove far enough to admit of the insertion or withdrawalof the rib or stretcher, and the ring is In figs. 4, 5, 12, and 13-thcOe11tre")'illg,g or L, of the notch or-crown-piece or runner is made ofmetal, leather, or other suitable material, and a slot or notch orcrown-piece, e or k, is out into or through it. By bringing this slot 0oppositeone of the slotsin thcnotch or crown-pieceD, or runner E or K,a. rib may ehsil be inserted or withdrawn, and'by turning thering'around until the notch or'crown-piece e or 7: is opposite one ofthe leaves which compose the wall of the annular groove in the notch orcrown-piece or runner, the ribs are fastened into position. The ring maybe secured from turning by dotting it at its junction with the leaves fwith a punch, or it may be secured in any other way deemed best. Thenotch or crown-picce or runner may also be extended downward or upward,and the metal or other ringput on'below, as seen in fig 12, a slotbeingmade in the ring as before, and the ring, when adjusted, and the ribsin, secured inn similar manner from turning around, so-as torelease theribs. I

In fig. 4, the spring-catches G G are shown in asomewhat modified form.They have hooks on the upper ends only, and these hooks shut or catchinto holes in the staff or tube, though they could be made to catchintoa groove in a sleeve, as in fig. 1, I prefer, however, to use the catchshown in fig. 1, as the sleeve strengthout; instead of weakens thestali', and the groove or shoulder extending entirely around the sleeve,there can be no trouble or delay in making the hooks catch.

Sutfieient shoulders, or projectionsmay be madein the ends of'the ribsand strctchers in a variety of ways, some of which are shown. It and ishow a globe or sphere struck up on the end of the rib or stretcher, andj a. cylinder, whose axis is perpendicular ,to the str'ctcher or rib.'-Tlicse, especialy the sphere, I consider the best.

Figs. 7 and 10 show other forms which may be used.

.Having thus fully described my invention, I claim- 1. The combination,with a notch or crown-piece or runner for umbrellas or pnrasols, havingan annular groove and radial slots in it for the ends of the ribsorstretchers to work in, of a ring of rubber, or other suitable elasticyielding material, forfastening said ribs or stretchers in said groove,while'at the same time one or more of the said ribs or strete'hers mayreadily be removed for repairs, substantially as setforth.

2; The combination, with a notch or crown-picce or runner of an umbrellaor Parasol, having an annular groove and radial slots in it for the endsof the ribs or. stretcher-s to work in, of a metal, leather, orothersuitable ring, for fastening said ribs or stretchers in saidgroove, said ring having one or more slots in its side, to permit of theintroduction or withdrawal of one or more of the ribs or'stretchers,substantially as set forth.

3. The combination, with the runner Id, of the spring-catches G G,operated in part or wholly by the Indiarubber or other elastic ring I,substantially as set forth.
